When, how, and why I began my interest in astronomy

by Victor Davis

As a general rule, I tend to value earned experiences more than accidental ones. That’s a pretty common view, it seems to me. The exhilaration of a summit view is heightened by appreciating the effort it took to get there. The view from a parking lot is less sublime than the vista from an untrammeled vantage point miles from the trailhead and reached by scrabbling uphill across fields of talus and scree. My car climbed Mount Washington (though I never collected the ubiquitous bumper sticker), but it’s the experience of hiking the Franconia Ridge that I particularly remember. These events took place, as you might imagine, many years ago when I was more agile and before my heart muscle had to be re-plumbed. 

Among these miniature adventures was a cross-country car trip nearly 50 years ago. I took off with a friend in his beat-up Chevrolet on a 6-week tour from our homes in Ohio to the West Coast and back. We had little agenda beyond spending a few weeks sponging off relatives; his in Montana and mine in northern California.  We subsisted mainly on a diet of cheeseburgers and french fried mushrooms, an unfortunate addiction that led more or less directly to my re-plumbing experience mentioned earlier.

I no longer remember the sequence of our travels, but at some point we ended up, as many tourists do, at the south rim of the Grand Canyon. Then as now, the visitors’ overlooks swarmed with people (also black flies), and though only about one percent of canyon visitors expend the effort to hike its trails, my friend and I decided to be among the enlightened few to “walk” down to the Colorado River and back. In one day. At midday in August. Signs warned of the foolhardiness of expecting to accomplish what seemed a modest 16-mile stroll (with a 4,400 foot change in elevation) in a single day and without proper preparation. No matter; we knew better than the ignorant rabble who turned back at the first rest area that it was important to wear long pants and to stay hydrated. We filled our one-quart water containers to the very top, and headed off down the Bright Angel Trail. The scenery was stunning, each of many switchbacks bringing into view a landscape different from the last, and just as beautiful. We were pretty baked by the time we got to the river, but that made its cold water that much more appealing. We played along the river for a few hours, splashing around and clambering over two-billion-year-old rocks. Then, with an exuberance and confidence available only to the profoundly ignorant, we headed back up the trail. 

Frolicking overlong at the river had the unintended benefit of sparing us the worst heat of the day. Nevertheless, the uphill climb was brutal. And nightfall came unbelievably quickly. Did I mention that our water supply was woefully inadequate? So there you have it: two inexperienced, barely-fit hikers, exhausted and dehydrated, hiking a steep and precarious trail in the dark.  At some point, and many details are mercifully lost to memory, we virtually collapsed along the trail. Lying flat on the ground, I looked up at the sky.

I’d never –and I mean NEVER – seen anything like it. I briefly entertained the idea that I was hallucinating. Stars shone everywhere. A few bright planets dazzled. There was this amazing gauzy band spanning the sky from one canyon rim to the other. What the heck was that? Every minute or so, a meteor streaked across the sky. A Perseid? It was all so beautiful, so dynamic, that I couldn’t stop watching. It was unforgettable, a sight I’ve tried to recapture, usually with disappointing results. What would I have to give up to enjoy such a view from where I live? That’s a pretty slippery slope. 

In subsequent years I have gone out of my way to experience astronomical sights and events, and to seek the company of others whose enthusiasm and expertise surpass my own. These efforts have enriched my life. But, my first experience of a starry night in a dark sky is what got me hooked on astronomy. When the hour gets past 10 pm and the temperature drops below about 50 degrees, remembering the rewarded efforts of these experiences is what gets my butt out of its comfy chair.

Rekindling My Love of Astronomy

by David J. Kaplan

I was born in the South Bronx. My parents each had two jobs, so we as kids were pretty much on our own. Saturday mornings my mother gave me fifty cents, pinned a label inside my coat with my name, address and telephone number. “If you get lost, ask a cop for directions.”

My friend Gary and I would take the subway, which was 10 cents, and travel all over the city. Transfers were free. We would take the Staten Island ferry for a nickel, go to the Bronx Zoo, it was free, or the Botanical Gardens, also free.

But our favorite destination was the Hayden planetarium and the Museum of Natural History, also free. We’d weigh ourselves on scales calibrated to how much we’d weigh on several of the planets and the moon. We’d exam giant meteorites, and wonder at the latest missiles sent aloft during the formative years of artificial satellites such as Explorer I.

Of course the sky show in the domed theater was the biggest attraction and for two kids whose imaginations were as infinite as space that was the hit of the day.

Before leaving the planetarium a visit to the gift shop was also a must. If we purchased anything on our limited budget, it was a giant postcard with images of Saturn and Jupiter, always a winner on Monday’s show and tell in our public school classroom.

Another of my friends received, for his 11th birthday, a three inch reflector telescope. Now that was a big deal. One evening we carried it to the rooftop of his apartment building and observed the moon. What a thrill!

Talk about imaginations as infinite as space. While observing the moon, it appeared as though something was heading toward it. It had a trail like the exhaust of a rocket ship. And then, it appeared as though it went behind the moon and reappeared on the opposite side. We thought we had made some extraordinary discovery. We ran downstairs to my friend’s apartment and (at 10 o’clock at night) called the Hayden Planetarium, excitedly telling the person who answered the phone of our great discovery. He replied, “I’m only the night watchman.”

So much for our great discovery.

In 1967, I was doing research for CBS News, the Special Events Unit. We we’re covering the launch of Apollo 8. The executive producer approached me and in an off-handed manner said, “See if you can find a sculpted globe of the moon. We’ll use it as a prop.”

It seemed a slight chance. I called several agencies in the Soviet Union. Hey, it was on CBS’s dime. I knew they had the first images of the far side of the moon and thought someone might have had the same idea, sculpting a model of the moon. Nyet, nyet and more nyets.

After speaking with folks at space agencies in Europe and having no luck, a colleague suggested I call Dr. Thomas Nicholson, an astronomer at the Hayden Planetarium, who later became its director. “Sure, there are two guys in the Bronx who just finished sculpting a model of the moon.”

What an extraordinary find. Graciously, they allowed us to use their sculpted moon (1,000,000:1) in inches. Every rill and crater, straight wall. It was all there.

We invited Dr. Nicholson to come to our studio and assist the lighting director. The moon was lit to duplicate how the astronauts would see it on their approach.

I would say that entire experience rekindled my love of astronomy.

keep your distance

I thought you might include in the newsletter, this social distancing advice for the astronomically inclined, which leaves the calculation as an exercise for the viewer.

Here are the relevant numbers:

Formula for the Schwartzschild radius of a black hole: R=2MG/c^2 (discounting charge and spin)

Gravitational constant (G): 6.67 X 10^-11 m^3/kg.s^2

Mass of Saturn: 5.68 X 10^26 kg

Have fun. My ZWO camera, which my wife ordered as a Christmas/Birthday gift for me, is finally due to arrive tomorrow! I figure that means dreary weather for the next month at least.

Your optimistic astro-buddy,

Vanity Cards

by Theodore R Frimet

That in my own humble opinion every Amateur Astronomer wearing a mask is a masked crusader for our mutual pursuit of life and liberty.

I’ve got nothing. I have been waiting to write that phrase for a few years now. Oft borrowed quotes from the media, steeds sometimes have to rise to the occasion. I too have to turn the page to the genius that is Chuck Lorre. “I’ve got nothing” appeared in one of his vaunted vanity cards.

I can’t seem to put the under age trace of the ministry of magic on it. Without a whiff, or a valid search engine (one that works), it is forever lost. My missing quote has become a tattered piece of laundry linen, flapping endlessly in Springs’ daily breeze.

No, I haven’t hunkered down in a battery of toilet paper. Yet, here I am, confessing my sins using intellectual confetti. Toilet paper, how-so-ever, could certainly make good confetti.

A shout out to the Mayor of New York: be sure to ban tossing unused toilet paper rolls onto the rank and file of those on the front lines! Once the touted parade on Broadway begins its ascent, marking the end of our recently endured pestilence, paper confetti would be best served, shredded then tossed lightly with a showering of gratitude and freshly shed tears.

Looking at the table before me, I vy Allegre (half read, my fellow amateur), a tome on molecular biology – untouched for months, and a few weeks worth of AAAS Science journals. No fodder here for the canon that is Sidereal Times. Wimper.

Off to my library then! Ok. The bookshelf in the living room should do. Social distancing is very important to both life and limb. I concede to what works. I hoof off a few, brew a hot coffee, and hunker down to…um…I’ve got nothing there, either.

K2, where are you, when the children need you the most?

Fritz, the destroyer of dobsonians, appears. He alights onto the table, and drops quickly to the ground. With a single bound, be leaps to the window. What is it, Fritz, old boy? What do you see?

I see nothing, Fritz replies. My hearing however is excellent. And of late, I am getting a little tired of your wimping about. What kind of amateur are you, anyway? Certainly not one that doesn’t spy the night sky and speak of his accomplishments!

Be wary your wordiness, humankind. Try to use your ears, as I do. Listen, learn and be aware of the difference between the truth and the contrivances of misdirection. The night sky is a record of truth. Pure and pristine, even the tidal forces surrounding the disk of a black hole can be dissected by science. Clouds be damned and use your imagination in lieu of your telescopic views.

Big Pussycat, aka Maybelle, sleeps on her low lying perch. Not being disturbed by my temporary insanity, she is blissfully unaware of the dob destroyers’ dominance over my cup of Joe. I take a sip. It is cold. How could that be? I just brewed it. “Twasinow”, says Fritz.

Enter K2.

K2 had not only fallen into a time well that lasted 10 or more time-space detents, she had knocked my coffee onto a time-loop. Hidden from my sight, K2 skirmished a slice of time. She bumped my coffee cup. The cup superimposed itself with the vibrations of K2’s temporal nexus.

It perplexes me that the physics of my coffee, in temporal isolation, would work out differently and become a cold cup of Joe. I sputter the drink back into its mug. Get up and brew another. Bad pussycat.

In Cheshire Cat style, K2 pops her head into my timeline. I am not amused. Taken off guard, I jump up. Fritz is puzzled as to the source of my anxiety. He too, runs from the room. Maybelle sleeps soundly. My coffee is ready.

For the past few weeks, off and on, I have been working away from home, doing a job that is considered essential. Each away-evening I give my brain the pre-sleep suggestion that I would like to solve faster-than-light travel all the while bending space-time to my will.

Due to the existential nature that is Freud, many poignant reveries revealed in deep sleep are compounded by the fractal nature of the dream. The deeper meaning, unlike Pascal, is lost upon my hippocampus. The best that has risen, not unlike the cream in my cup, is me traveling upon a road. Slipping to one side or the other, correcting the gait of my car, we encroach upon a tunnel. I enter it as I awake from slumber. And once again, I’ve got nothing. ‘Twasilater.

Astronomy in the Time of Coronavirus
AAAP’s operations at both Peyton Hall on campus and the Observatory at Washington Crossing State Park are closed until the coronavirus crisis normalizes and group gatherings are once again allowed. We’re probably all feeling stress from the disruptions. I deeply hope that you and yours are staying healthy and making the best of it during this difficult period.

AAAP Officer Elections coming up
In order to conduct elections of officers in keeping with our constitution and by-laws, I have asked John Church to be nominations chair. He will report this month on the status of a slate. The elections will be conducted via e-mail or survey on-line since we cannot meet in person. I am in discussions now with the Board regarding process and will be communicating the election plan to members by May.

Starlight for Our Eyes
Science and the study and practice of astronomy can be a great theme to pursue while we are immobilized at home with social distancing in place. Of course, it would help a little if our local skies would clear up, our retinas need starlight. Unfortunately, most professional as well as amateur centers for astronomy are shuttered. The entire mountain top observatory cluster in Chile (Cerro Tololo) where I do remote astronomy is now shut down, like the rest of the planet. So the image below is from the last data we were able to get.

NGC 2736 (image below) is part of a large supernova remnant in the constellation Vela in the southern sky, 820 light years away – close by astronomical standards. It was first described by England’s Sir John Herschel in March 1835 during his 4 year period doing astronomy in South Africa. Sometimes called the Pencil Nebula, NGC 2736 is a glowing sheet of gases and particles ejected from the supernova event about 11,000 years ago. Today a pulsar sits at the center of the original star. The red regions in the image below are mainly ionized hydrogen and the blue ionized oxygen, gases ejected from the inner layers of the star when it exploded. According to David Malin, the section seen here is part of a roughly spherical shell outlining the expansion of the supernova explosion, but that connection is really only visible in X-ray telescope images. The connectivity in optical wavelengths is obscured by dust from the explosion. The exploding star is thought to have quickly reached a brightness over 200 times that of Venus. Our human ancestors and animals and birds alike would have been dazzled by the sudden appearance of a daystar in 9000 BC, much as we are amazed by its remnants in the deep sky today.

From the Program Chair

by Ira Polans, Program Chair

All monthly club meetings have been cancelled due to Princeton University closing its campus and the need to social distance. I have reached out to the speakers affected by the cancellation (March, April, and May) and all have agreed in principle to give their talks once things return to normal.

While we’re going through this difficult time please stay safe and healthy.

Observatory Public Nights Postponed. Our Skies Remain Open

by Dave Skitt, Observatory Chairperson

The State of New Jersey closed our public state park buildings. This is part of the COVID 19 virus response. AAAP delayed the opening of our observatory for Friday Night Public Observing for your safety. This delay will remain in effect until NJ lifts the group congregation restriction.

All is not lost; the skies will remain open. How you might ask? Through the marvel of telescope technology and the internet.

AAAP recently assembled “the outreach scope” from a pre-owned Orion ED 80 refractor and iOptron AZM Pro mount. We equipped it with a flip mirror and the clubs’ Starlight Xpress Ultrastar C camera.

Appearing in this months edition of Sidereal Times is, Novice EAA Imager Captures Rare, Unseen Astronomical Phenomenon. There I describe the pleasure to dabble with the scope and learn how to use it. Inspired by my church switching to online video services, I have now learned how to broadcast live streaming video from the Ultrastar camera to the internet.

I invite you to check out our club’s Twitter page (@Princetonastro). Our social media is your temporary observatory gateway. Using Twitter, we will observe together over the next several Friday nights. I will be live broadcasting night sky views from my home observatory, weather permitting.

Together we wait for the AAAP observatory to re-open. There, we can share the stellar photons at the eyepiece. For the meanwhile, I hope you will join me in this technological substitute.

Nominations for AAAP Officers for 2020-21

by John Church, Nominations Chair

Dear Members,

Director Rex Parker has kindly asked me to serve as Nominations Chair for our upcoming May election. I am therefore very pleased to report that all of our present officers have agreed to be nominated for another term. In my estimation they have all performed admirably in their respective posts, often above and beyond the call of duty.

The slate is as follows:

For Director: Rex Parker
For Assistant Director: Larry Kane
For Secretary: John Miller
For Treasurer: Michael Mitrano
For Program Chair: Ira Polans
For Observatory Chair: Dave Skitt
For Outreach Chair: Gene Allen

As always, additional nominations can be made by any member in good standing. However, because we will not be able to meet in Peyton Hall to actually conduct the election in May, arrangements are being made to accept any additional nominations and conduct the election electronically. Please stay tuned to Sidereal Times for further details.

In this difficult time we need to keep the club up and running to the best of our ability. It is unfortunate that we cannot presently meet in person, hear all those wonderful programs that Ira has been arranging, and share anecdotes and personal greetings, but this too shall pass. In the meantime, we are still able to stay in touch electronically. Thank goodness the Coronavirus has not infected our computers!

Freeman J. Dyson: A Personal Remembrance

by John Church

The Amateur Astronomers Association of Princeton joins the world in mourning the passing of renowned mathematical physicist and noted author Freeman J. Dyson on February 28 of this year at the age of 96.

Freeman, an Emeritus Professor at the Institute for Advanced Study in Princeton, was a great supporter of the role of amateurs in astronomy. A member of the AAAP for nearly 50 years, he helped us build our observatory in Washington Crossing State Park as well as giving the club many lectures in the Peyton Hall auditorium, which was always filled to capacity for such treats.

I first met Freeman in the early 1970’s after having summarized an article of his entitled “Energy in the Universe.” I remember telephoning him (with some trepidation) and asking if he would consider joining the AAAP. He responded that he would indeed be interested. This led to a friendship that lasted nearly half a century, of which more anon.

Here are some abridged selections from back issues of our newsletter Sidereal Times that mention Freeman’s long involvement with the club:

The Nov. 10, 1973 transit of Mercury was observed and timed from John Church’s driveway, using the club’s 6-inch refractor. Present were Freeman Dyson and Tullio Regge of the Institute for Advanced Study. A report was sent to Sky and Telescope, and the timings were published. With Freeman’s help, plans were proceeding to place a club observatory in a modified aluminum garage at the Institute that would be put on roll-off tracks. Member and civil engineer Karl Koehler prepared detailed drawings for the project. This proposal was not adopted due to finding that the Institute would have required construction to be performed by outside labor, which the AAAP could not have afforded.

AAAP member and Institute for Advanced Study Prof. Freeman Dyson was the speaker for the September 1986 meeting.

Prof. Freeman Dyson, long-time AAAP member who participated in the observatory construction in the late ‘70’s, presented a talk entitled “Hunting Comets and Planets” at the November 1990 meeting.

Prof. and AAAP member Freeman Dyson spoke to the AAAP on the subject of “Revolutions in Astronomy” at the December 1993 meeting.

AAAP held its 40th Anniversary Dinner at the Frist Center on the Princeton campus in November 2002. Freeman Dyson, one of the Washington Crossing observatory’s builders, spoke on “A New Way To Look For Life In Cold Places Far From The Sun.”

Our 50th Anniversary Dinner was held on the campus of the Institute in November 2012, at which Freeman also spoke.

On a personal note, my wife and I were invited to the Institute’s Sept. 2013 “Dreams of Earth and Sky” celebration of Freeman’s career. At the banquet on the final evening I gave a few remarks on Freeman’s contributions to our club, including the part he took in the building of our observatory in Washington Crossing State Park in 1977 and 1978. He was there at the site on many Saturdays. Here is a photo of him helping to dig the trench for the foundation:

On one fine Saturday afternoon, Freeman and I laid the fourth tier of cinder blocks in the east wall of the observatory. He helped with the project in many other ways as well.

I had the privilege of meeting privately with Freeman in his Institute office on many occasions when we discussed various topics in physics, astronomy, and cosmology. (Unfortunately, I haven’t kept written notes of our discussions.) On these occasions he would kindly host me for lunch in the Institute’s cafeteria. He very generously gave of his time to critique my draft of a personal memoir entitled From Eve and Morning that I issued privately in 2003. I have several of his books that he signed for me.

Freeman’s talents as a superbly clear and concise writer in multitudes of areas not necessarily related to physics are so well known that it would be superfluous for me to comment further here. As but one example, he served for many years as an invited contributor to the New York Review of Books. These wonderfully-written pieces engendered many replies, not always in agreement with his own views on subjects such as climate change and the role of enormous projects. He was a fan of small projects done inexpensively by individuals and small teams.

To conclude, here is a quotation from one of Freeman’s articles in the New York Review of Books on the subject of “Final Theories in Physics.” This is, I think, a good summary of his philosophy.

I find the idea of a Final Theory repugnant because it diminishes both the richness of nature and the richness of human destiny. I prefer to live in a universe full of inexhaustible mysteries, and to belong to a species destined for inexhaustible intellectual growth.

We in the Amateur Astronomers Association of Princeton will fondly remember Freeman and his many contributions to the welfare of our club as well as in so many other areas.

– John Church

Novice EAA Imager Captures Rare, Unseen Astronomical Phenomenon

by Dave Skitt, Observatory Chairperson

If you’ve been reading my emails lately, you know that Dr. Rex Parker, PhD, and I conducted a Keyholder training session on Sunday, March 8, 2020.  We focused on the clubs’ expanding Electronically Assisted Astronomy (EAA) capabilities.  

As a novice EAA imager, I thought the session went very well.  All in attendance exclaimed how rapidly the new EAA technology was evolving and broadening the reach of what can be seen with relatively short exposures.  Despite the nearly full moon, the images of M42 with the ZWO camera on the C14 and the Ultrastar camera on the cOrion ADA, 80mm outreach scope were nearly identical.  The only difference were the exposure times:  5 seconds with the C14 versus 24 with the outreach scope.

After the session, I stayed behind to practice some more with the outreach scope/camera and iOptron AZM Pro mount. I decided to really test the limits and image some objects in the constellation between Virgo and Canes Virenatici.  

Home of globular cluster, M53, the Black Eye galaxy (M64), the Coma Pinwheel galaxy (M99) and the Needle galaxy (NGC 4565), the constellation Coma Viranices (“Viranices Hair”) presents some fine challenges for EAA.  I wanted to narrow down what camera settings would work best on this spread of objects.

I started my adventure on M53.  But not before I synced the mount on Denebola in Leo and tweaked my focus on nearby Cor Caroli with a N95 focus mask.  The AZMP mount got M53 dead on!  The Ultrastars’ stacked 20 second exposures revealed it to be a “rather vivid and round nebula of sars”, just as Johann Bode had described it when he discovered it in 1775.  Awesome!

Next up, M64.  Not nearly dead on but toggling the flip mirror helped me center the fuzzy oval in the eyepiece.  Flip back to the camera.   Wow!  Here, 30 second stacked exposures revealed M64s’ irregular shape, uneven brightness and cool texture.  The dark “Black Eye” dust feature was stunning.

Since it was getting late, I decided to skip “the Pins” (M99) and go straight to “the Needle”, NGC 4565.   This would be a good challenge to end the night.  

Now the AZMP’s slews are quiet.  Really quiet.  So much so that I wasn’t sure that it had moved far enough to hit the Needle.  Rushing in the cold, I typed in 14 days seconds in the exposure box and hit enter.  What appeared on the screen took my breath away.  I shivered.

Close up, the image looked like a comet. But when viewed six feet from the screen, it looked like a planetary nebula.  Had I not cleared the image cache before slewing?  Could it be both?  I took a screenshot and texted it to Tom Swords, a passionate comet hunter.  “That’s not a comet”, Tom replied.

I then texted the image to Dr. Parker along with the RA/DEC coordinates (16h 55m 33.86s/-41o 50’ 51.6”).  His extensive background in astro-imaging lead him to believe I had stumbled upon some novel astronomical phenomena.  He immediately called Dr. David Nyell at Central Management for Official Sightings and sent him the image and data.  

Twenty-four hours later, Dr. D. Nyell replied.  “We at CMOS can only state that the object observed at those coordinates is a presumptive positive sighting.  The data will be forwarded to the Copernicus Celestial Discovery Center via their Hotline.  Please refrain from additional observations until April 5th.  At such time we will reassess our position”.  

Early Tuesday morning, I received a frantic phone call from someone who identified herself as Vira Di’ Seaz.  She exclaimed “the C-CD-C has confirmed that you have caught the CO-VID-EAA-19 virus, aka, the CoronEAA virus.  Please self-quarantine yourself at the observatory for 14 days for further observation.”  

“Fourteen Days?  What do I do after 14 days?”, I blurted out.

After a short pause, Vira replied, “Well…, Corona Borealis will be higher in the sky by then.  You could poke around there with your telescope until this whole thing blows over…”!

April Fools.

P.S.:  The coordinates given above are for NGC 6231 located in Scorpius.  It is labeled in Stellarium planetarium software as the “False Comet Nebula”.

At Home in A Dome

by William Murray

Since I’m stuck at home for the foreseeable future (as is everyone else in the world) I decided that astronomy is the best occupation for my time. Here are the results of some imaging I’ve been doing. The monochrome images are with an ATIK Infinity video camera on my Astro-Physics 130 mm Starfire GT refractor:
